Example 1 with ResourceFieldAccessor

use of io.crnk.core.engine.information.resource.ResourceFieldAccessor in project crnk-framework by crnk-project.

the class HistoryFieldContributor method getResourceFields.

@Override
public List<ResourceField> getResourceFields(ResourceFieldContributorContext context) {
    // this method could be omitted if the history field is added regularly to Project and Task resource. This would be
    // simpler and recommended, but may not always be possible. Here we demonstrate doing it dynamically.

    fieldBuilder.name("history");
    fieldBuilder.genericType(new TypeToken<List<History>>() {
    }.getType());
    fieldBuilder.oppositeResourceType("history");
    fieldBuilder.fieldType(ResourceFieldType.RELATIONSHIP);
    // field values are "null" on resource and we make use of automated lookup to the relationship repository
    // instead:
    fieldBuilder.lookupIncludeBehavior(LookupIncludeBehavior.AUTOMATICALLY_ALWAYS);
    fieldBuilder.accessor(new ResourceFieldAccessor() {
